Cybersecurity Incident Response (IR)

What is Incident Response?

Incident response is an action taken to identify, contain, and manage a cybersecurity incident. Cybersecurity incident response involves multiple phases including preparation, analysis, mitigation, and evaluation. Preparation is the first phase. It requires the development of policies, procedures, and training, which will help an organization respond to a cybersecurity incident. The second phase is analysis. This is when an organization must identify what happened and why it happened. It involves identifying and analyzing data, determining the extent of the damage, and creating a plan of action to mitigate future damage. The third phase is mitigation. This is where an organization takes measures to prevent further damage. This includes blocking access to compromised systems, patching systems, and notifying users. The fourth phase is evaluation. This is where an organization evaluates the impact of the incident and develops a plan of remediation. Once all phases are complete, an organization is ready to move on with its normal business operations.

Importance of Incident Response

Incident response is a proactive approach to minimize the risk of a cybersecurity attack or incident. A cybersecurity incident can be caused by any number of factors, including human error, system vulnerabilities, network weaknesses, and advanced persistent threats. Incidents that require extensive recovery can be costly, so it is important to ensure that your business is protected from these threats. A cybersecurity incident response is a proactive approach to minimize the risk of a cybersecurity attack or incident.

The Six Steps of the Incident Response Lifecycle

There are six steps to incident response. They occur in a cycle each time an incident happens. The steps are:

  • Preparation of Systems and Procedures
  • Identification of Incidents
  • Containment of Attackers and Incident Activity
  • Eradication of Attackers and Re-Entry Options
  • Recovery from Incidents, Including Restoration of Systems
  • Lessons Learned and Application of Feedback to the Next Round of Preparation

What is an Incident Response Team?

Is a Cybersecurity Incident Response Team Needed? A cybersecurity incident response team can provide assistance to an organization after a cyber attack occurs. These teams are comprised of experienced security professionals who are capable of determining the scope of an attack and developing an action plan to contain and recover from the damage done. A cybersecurity incident response team can help you determine the best course of action in order to keep your business safe. For example, if your organization is a victim of a data breach, you will want to make sure your data is secure. Cybersecurity incident response teams will be able to assist in implementing an action plan that will safeguard your company from future attacks.

What is an Incident Response Plan?

An incident response plan, also known as an IRP, is a document that details the steps a company must take in the event of a cybersecurity incident. The goal of an IRP is to identify any weaknesses in the company’s system, minimize damage, and prevent future incidents.

In order to establish an effective incident response plan, it is important to know what an incident is and how it might happen. There are four broad categories of incidents:

  • Malicious incidents — an attack by an individual or group to intentionally damage or disrupt computer systems, networks, or data.
  • Human error incidents — a failure in human judgment or action, such as a user unintentionally pressing a wrong key on a keyboard.
  • Technical incidents — a breakdown in a computer system’s hardware or software that causes unintended or undesired results.
  • Natural disasters — an event that disrupts computer systems without an attacker’s involvement, such as a fire or earthquake.

To put it simply, an IRP is a step-by-step plan for responding to an incident. It identifies the specific roles and responsibilities of each member of the organization, the steps that should be taken to mitigate the impact of an incident, and the resources that are needed to accomplish those tasks.

A cybersecurity incident response plan is much more than just a checklist of tasks to be performed. It is a strategic plan that outlines how the company will respond to a cybersecurity incident. It is important to understand the difference between a cybersecurity incident response plan and a traditional business continuity plan. A cybersecurity incident response plan will focus on the steps that need to be taken after an actual cyberattack is detected, while a business continuity plan will be used to prepare for a potential natural disaster or other disruptive events. 

Why is an Incident Response Plan Important?

A well-written incident response plan can protect you against any type of attack. In the event of an incident or data breach, you want to be protected. This includes your physical assets, intellectual property, and even your reputation. It is imperative to have a written incident response plan in place to protect yourself from any attack. Cybersecurity experts have said that the best way to prevent an attack is to have a well-written plan in place. A good incident response plan should include:

  •  Who will respond?
  • What information will be gathered?
  • What actions will be taken?
  • Who will conduct these actions?
  • How will the results of the actions be evaluated?

A good incident response plan is not simply about preventing a breach, it is about making sure you are protected in the event of an incident. The best way to prevent an attack is to have a well-written plan in place. At Cyber Sleuth Security, we have experience writing and creating incident response plans for businesses of all sizes. We help companies identify their weaknesses and develop a plan to avoid a breach. If a breach occurs, we are ready to help you in the aftermath. Contact us today to learn more.

Most Organizations Lack a Plan

The need for incident response plans isn’t exactly news. But according to a recent survey conducted by security vendor Ponemon Institute, it appears that many organizations still aren’t taking the necessary steps toward developing a comprehensive plan.

According to the study, 77 percent of respondents said they lacked a formal incident response plan that applies consistently throughout their organizations. And among those that did have such a plan, only 32 percent described their efforts as mature.

Among those that did have an IR plan, only 55 percent said their teams had been trained in how to respond to cyberattacks.

And while most respondents reported having some sort of incident response team, just over half said their teams consisted of fewer than 10 people.

Those numbers are concerning, especially considering that 57 percent of organizations say the length of the time it takes to resolve cyber incidents in the organization is growing longer, and 65 percent say their attacks are becoming increasingly severe.


What is the SANS Incident Response Framework?

The SANS Institute provides a framework for responding to incidents. It consists of six phases: preparation, identification, containment, eradication, recovery, and lessons learned. These are broken down further into subcategories such as investigation, communication, and remediation. 

What is the NIST Incident Response Framework?

The National Institute of Standards and Technology (NIST) recently published a comprehensive guide to incident response called the Cybersecurity Framework. This document outlines how organizations should prepare themselves for cyberattacks and what actions they should take during an attack. In addition to guiding incident response planning, it also provides detailed instructions on how to build an effective incident response team.

This framework condenses the six steps used by the SANS framework into four: preparation, detection and analysis, mitigation, and recovery. These steps are designed to help organizations understand the nature of attacks, establish an incident response plan, identify vulnerabilities, develop countermeasures, and recover from incidents.
